DRAIN-PIPE.

Application filed September 14, 1916. Serial No. 120,078.

To all whom it may concern:

Be it known that I, SAMUEL F. Gross, a citizen of the United States, residing at Portland, county of Multnomah, State of Oregon, have invented certain new and useful Improvements in Drain-Pipes, of which the following is a specification.

My invention relates to drain pipes for buildings in general, and particularly to devices whereby floor areas and the like may be drained into such pipes.

The object of my invention is to provide a device whereby the floor .areasjand the like may be drained into drainage pipes or sewers automatically and continuously, and whereby the trap 'may be continuously flushed; to produce a device that shall prevent gas or water from backing up into the area being drained; and to produce a device that maybe easily connected intoany line of drainage pipe or sewer, that may be adjustable to various depths of location of the drainage pipe or sewer below the floor level, and that shall be simple, cheap to manufacture, economical to install, and positive and automatic in action. I

I accomplish the above objects and other desirable results by means of the construc tion illustrated in the accompanying drawing, which therefore becomes a part of this application for Letters Patent, like characters of reference indicating like parts throughout the several views thereof,"and in which; V

Figure 1 is aside elevation of my device as constructed of pipe fittings, and is shown partially in section'to bestillustrate .the construction. 7

Figs. 2 and 3 are sections upon lines 2-2 and 3-3 respectively of Fig. 1, and are shown in correct-relative vertical positions to illustrate the principle of operation of my device, as hereinafter disclosed.

Fig. i is 'a'side'elevation of a modified form of my device as manufactured or cast in one piece, being partially shown insection.

llig. 5 is an end elevation of the subject matter of F ig, 4:.

Fig. 6 isa plan view of the subject matter of Fig. 4.. V

In general myinvention consists of a main member or pipe adapted to be in.- serted into the run of any suitable drain pipe, and having-a fall or declination inter mediate the ends thereof, a bypass pipe-connecting orifices within said first mentioned pipe, and having therein a Water sealed trap, and an adjustable piperising from said trapand terminating at the fioo'r level to be drained; v 1

In the drawing the inclined portion of said main pipe is indicated by 7, and the ends thereof fonconnecting the same-into a line of dram pipe by 8 and 9, said ends being formed similar to the ends of ordinary drain pipe well known to the art.

' Intermediate said ends Sand 9 are two orifices 10 and 11, intowhich are connected the ends of a by-pass pipe.

The orifice 10 is located adjacent the higher end of pipe 7 and slightly around the sectional contour of said pipev from the bottom thereof, asshown in Fig. 2, a screen 12 being disposed oversaid orifice for the purpose of excluding solid matter from the bypass pipe. l

The lowest point of orifice. 10 is disposed below the normal water level in pipe 7, as

shown in Fig. 2. V I w The purpose of removing the-orifice 10 from the bottom of pipe 7 as shown in Fig. 2 is to allow solid matter in the bottom of pipe 7 to pass the orifice 10 freely and without any tendency to enter said orifice.

I The orifice 11 is located adjacent jthLe lower end of pipe Y, and so far around the sectional contour of said pipe from the bottom thereof as to enter pipe 7 above the normal water level therein, as shown in Fig. 3.

Orifices 10 and ll'are such relative positions uponpipe 7- that the lowest point of orifice 10 is above the highest point of Patented Nov. 6, 1191 7. v

orifice 11, as shown in Figs. 1, 2, 3 and 4, this being for the purpose of establishing a flow of water through the by-pass pipe.

The by-pass pipe consists of a substantially vertically disposed portion 13 connecting with orifice 10 in pipe 7, a water sealed trap portion 14, and a substantially horizontally disposed portion 15 connecting with orifice 11 in pipe 7, as shown in Figs. 1 and a.

Connecting with said water sealed trap 14 is a riser pipe 16 having therein a chamber 17 containing a float ball valve 18, and upon the upper end thereof is a packing nut or gland l9.

Extending through said pa'cking nut 19 is a vertically adjustable pipe 20 forming substantially an extension ofr-iser pipe 16, the lower end thereof entering chamber 17 and 'coacting with ball'valve 18 to form a seal against back pressure water entering pipe 20.

Upon'the upper end of pipe 20 is secured a drain cup or cap 21 of suitable construction, that shown in'the drawings being of bell shape with screen bars 22 over the mouth thereof.

The operation of my device is as follows.

The pipe -7 being connected into a sewer or drain pipe, water and sewerage will flow therethrou'gh, the'solidmatter passing orifice 10 as previously described, and a cer tain percentage of water will pass through, orifice10 into the bypass pipe.

The water thus admitted into the by-pass pipe will seal the trap 14 and, by reason of the relative positions of orifices 10 and 11 previously described, will discharge through orifice 11 into pipe'T.

Thus 'while a perfect water seal is 1naintained in trap 14 a continual flow is also maintained therethrough which keeps the watcr'in trap let always fresh and prevents the fouling of the same.

The water from the area to be drained is discharged into-the trap 14: by means of drain cap 21, pipe 20, chamber 17 and riser pipe 16.

The ball valve 18 normally rests upon lugs 23, or other convenient device, near the bottom of the chamber, thus allowing an unobstructed flow of water through the chamber 17 and the'pipes connected thereto.

In case a back pressure within-the sewer or drain pipe causes the bypass pipe and the parts connected therewith to fill, the

ball valve will float upward and coming into'contact with the lowerend of pipe 20 will seal'the same, as shown in dotted lines in Figs. 1 and 4, and thus prevent any over flowthrough the pipe 20 into the area being drained, due to the back pressure.

My invention -maybe made of any size and constructed of any materials deemed convenient and suitable for a device of this character, and while I have illustrated and described a form of construction and arrangement of parts found desirable in nia terializing my invention, I wish to include in this application for Letters Patent all mechanical equivalents and substitutes that may fairly be considered to come within the scope and purview of my invention as defined in the appended claims.

Having disclosed my invention so that others skilled in the art may be enabled to construct and to use the same, what I claim as new and desire to secure by Letters Patent is 1. In a drainage device, a main pipe disposed upon an incline and adapted to be connected into a lineof drain pipe; a bypass pipe connected into said main pipe; a water scaled-trap in said by-pass pipe; a vertical riser pipe connected into said trap and adapted to drain afloor area or the like.

2-. A drainage device comprising a vertical drain pipe, and-a float valve in said drain pipe, in combination with a main pipe disposedupon an incline, and a bypass "connected into said main pipe and including therein a trap at the bottom ofthe drain pipe.

3. In a device'for draining floors and the li-ke,-a vertically disposed drain pipe with a water sealed t'raptherein; an inclined pipe adjacent thereto; a pipe intermediate said trap and theupper portion of said inclined pipe; and a pipe intermediate said trap and the lower portion of said inclined pipe; said last mentioned intermediate pipes forming a continuous bypass includingsaid trap.

4. A drainage device having therein a vertically disposed drain passageway with a water sealed trap therein, an inclined drain passageway, a passageway connecting said trap with the upper portion. of said inclinedpassageway, and a passageway con necting said trap with the lower portion of said inclined passageway.

5. In a drainage device, an inclined member; a member forming a bypass fronrthe upper portion to the lower portion ofsaid inclined member and having a water sealed trap therein and means to connect said trap with author or the like for the purpose of draining the same.

6. In a drainage pipe, a main pipe 'd-isposed upon an incline, and having an exit orifice adjacent'th'e upper end thereof and an intake orifice adjacent the lower end thereof, said exit orifice "being disposed slightly abovethe'bottom of said inclined pipe and partially below the water level therein, said intakebrifice being disposed above the water-levelin said inclined pipe andbelow the levelcf said exit orifice; a

by-pass pipe connecting said exit and said intake orifices; a water sealed trap in said by-pass pipe; and a drain pipe connecting with said trap.

7 A drainage device comprising an inclined member inserted in a sewer pipe; means for continuously diverting a portion of the liquid flowing through said sewer from the upper portion of said inclined member to the lower portion thereof outside of said member; a water sealed trap forming a portion of said means; and means to connect said trap to any device to be drained.

In witness whereof I claim the foregoing to be my own I hereunto affix my signature in the presence of two subscribing witnesses, at Portland, county of Multnomah, State of Oregon, this 6th day of September, 1916.
